Dr. Li is fascinated in developing and applying (1) mechanics-based advanced structural models, and (2) probabilistic and statistical methods to engineering risk/reliability problems in the field of structural engineering. This serves to assist decision-making in the process of probability-based design, retrofit, and maintenance of a wide range of structures (e.g., concrete bridges, masonry buildings, steel pipelines, etc.) in the face of uncertainty. He is also interested in inverse engineering problems (e.g., structural design optimization in earthquake engineering, nonlinear FE model updating using field-recorded and experimental data, data-driven model learning problems, probabilistic diagnosis and prognosis for structural system and mechanical equipment).
